How does obama define the american dream?

Barack Obama defines the American dream as the idea that anyone who lives in the United States can achieve success, through hard work, determination, and rise from the very beginning, regardless of his/her origin, race, financial situation, etc.  

Explanation:

Obama's figure is the best example of his vision of the American dream, as he came from a humble family and became the first Afro-American president of the USA.

He highlights the opportunity, considering that all citizens should have equal rights and be able to get rich and successful. The most important thing is to give an opportunity to everybody.

To achieve the American dream society should create equal opportunities for everyone, people should open to each other and appreciate cooperative efforts rather than individual efforts.
